Description David Tardon 2019-10-18 11:14:01 UTC

This bug was initially created as a copy of Bug #1722182

I am copying this bug because: 
It is still a bug in 8.x.


Description of problem:
It is possible to use a keydev to unlock a luks root volume at boot since https://github.com/lnykryn/systemd-rhel/pull/231 (#1619743)
However, when the device used as keydev is not present (for example an unplugged usb drive) it is not possible to provide a password as fallback.

Version-Release number of selected component (if applicable):
systemd-219-62.el7_6.6.src.rpm

How reproducible:
Always

Steps to Reproduce:
1. Configure a keydev for a luks root volume
2. Remove the device that is used as keydev
3. Reboot

Actual results:
After a very long timeout the dracut shell starts.

Expected results:
After a reasonable timeout the user is asked for a password. When entering the correct password the system boots normally.

Additional info:
Attached a patch for systemd-219-62.el7_6.6.src.rpm that allows the user to enter a password when the keydev device is not present.
